Configure ULS logs to rollover after 60 minutes
By default SharePoint rolls over it’s Unified Logging Service (ULS) logs every 30 minutes. I would like to reduce the number of log files so will increase the rollover to 60 minutes by using the Set-SPDiagnosticConfig PowerShell command:
Set-SPDiagnosticConfig –LogCutInterval 60
To view the current configuration I can use the Get-SPDiagnosticConfig PowerShell command:
(Get-SPDiagnosticConfig).LogCutInterval
Note: The value specified for the interval must be an integer and not greater than 1440.
